TPS74618PQWDRVRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6(2x2)

TPS74618PQWDRVRQ1 from Texas Instruments, in a WSON-6(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Regulated output voltage pin; supports 0 to 1 A output current and requires output capacitor to ground for stability.
2 NC unconnected No internal connection; grounding recommended for improved thermal performance.
3 GND power_in Ground reference pin.
4 EN input Enable input; drive above VEN(HI) to enable or below VEN(LO) to disable; rated 0 to 6.0 V.
5 PG tri_state Open-drain power-good output with 150-µs delay; maximum current ±10 mA.
6 IN power_in Input supply voltage; accepts 1.5 to 6.0 V and requires 1 µF or larger ceramic capacitor to ground.
7 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
